Abstract: An article, such as a containment system (10), having sides (12) with walls (2) or (24) is made; in one method by using cast, cooled, melted, radioactive metal components where the melted metal has a specific activity over 130 Bq/g; or by providing a contaminated material in the form of a solid, liquid or mixture, and then mixing the contaminated material, to which no more than about 15 weight % of uncontaminated material has been reacted, with a binder, followed by forming the composition into a containment system and then curing it into a mass which contains both contaminated material, and uncontaminated binder acting as a matrix for the contaminated material. This article need not be a containment system but can be a wide variety of objects which are made out of radioactive waste, hazardous waste, and their mixtures.

Abstract: As shown in FIGS. 8 and 9, the instant invention provides a concave filter 530 which comprises two oppositely disposed geotextile fabric sheets 560A and 560B. Fabric sheets 560A and 560B are porous for filtering the liquid from the slurry solids and may be fabricated from a geotextile material such as the material composing filter sheets 330a and 330b (see FIG. 4). Disposed between fabric sheets 560A and 560B is at least one drainage grid 350 such as the drainage grid 350 illustrated in FIGS. 4 and 4A.

Abstract: Apparatus and method for dewatering radioactive waste slurry solids. The apparatus includes a vacuum pump for applying a vacuum to a suitable flexible filter and collapsible membrane combination in which the slurry solids are contained so that the slurry solids are compressively dewatered when the vacuum is applied. The apparatus further includes a container for suitably storing the resulting dewatered slurry solids.

Abstract: Volumetrically efficient radioative waste container apparatus, wherein the container apparatus includes a plurality of open pockets recessed into the outside surface of the container, a plurality of lifting lugs each completely disposed within and attached to each pocket and further includes a container adaptor capable of being connected to the lifting lugs for reacting torque and lifting loads and for lifting the container. An opening is provided in the container for filling the container with waste. A coupling is provided in the opening as an attachment point for a mixing blade assembly which mixes and homogenizes the waste transferred into the container. A motor is connected to the adaptor for rotating the mixing blade. The adaptor further includes arms and lifting brackets for transferring the motor's torque to the lifting lugs. The adaptor also includes stiffeners attached to the motor, the arms, and to the lifting brackets for resisting the torque transferred to the lifting lugs.
